Anecdotal experience has suggested that there is a higher frequency of maxillofacial injuries among motor vehicle collisions involving moose.
A retrospective cohort study design was used to investigate the incidence of various injuries resulting from moose-motor vehicle collisions versus other high-speed motor vehicle collisions.
A chart review was conducted among patients presenting to a Canadian regional trauma centre during the five-year period from 1996 to 2000.
Fifty-seven moose-motor vehicle collisions were identified; 121 high-speed collisions were randomly selected as a control group. Demographic, collision and injury data were collected from these charts and statistically analyzed. The general demographic features of the two groups were similar. Moose collisions were typically frontal impact resulting in windshield damage. The overall injury severity was similar in both groups. Likewise, the frequency of intracranial, spinal, thoracic and extremity injuries was similar for both groups. The group involved in collisions with moose, however, was 1.8 times more likely then controls to sustain a maxillofacial injury (P=0.004) and four times more likely to sustain a maxillofacial fracture (P=0.006).
Occupants of motor vehicles colliding with moose are more likely to sustain maxillofacial injuries than those involved in other types of motor vehicle collisions. It is speculated that this distribution of injuries relates to the mechanism of collision with these large mammals with a high centre of gravity.
轶事经验表明，在涉及驼鹿的机动车碰撞事故中，颌面损伤的发生率较高。
采用回顾性队列研究设计，调查驼鹿与机动车碰撞导致的各种损伤的发生率与其他高速机动车碰撞的发生率。
对1996年至2000年这五年间到加拿大某地区创伤中心就诊的患者进行病历回顾。
共识别出57起驼鹿与机动车碰撞事故；随机选取121起高速碰撞事故作为对照组。从这些病历中收集人口统计学、碰撞和损伤数据并进行统计分析。两组的一般人口统计学特征相似。驼鹿碰撞事故通常为正面碰撞，导致挡风玻璃损坏。两组的总体损伤严重程度相似。同样，两组的颅内、脊柱、胸部和四肢损伤的发生率也相似。然而，与驼鹿碰撞的组发生颌面损伤的可能性是对照组的1.8倍（P = 0.004），发生颌面骨折的可能性是对照组的4倍（P = 0.006）。
与驼鹿碰撞的机动车驾乘人员比其他类型机动车碰撞事故的驾乘人员更容易发生颌面损伤。据推测，这种损伤分布与与这些重心高的大型哺乳动物的碰撞机制有关。
